It depends on the crystal and where you are buying it from.
Yes, pixies have wands. They use their wands to do a variety of things. Their wands have very limited magic, so they can not do much with them besides levitating things.
If I understand your question, personalising a wand can take many forms. Adding a crystal of your choice, carving symbols and designs into it, wrapping it in a "cage" of wiring of your choosing (which is very much like added a crystal in that you would also be using the metal's own properties to add to the wands own vibrations). If you are going to cage your wand though remember to not enclose the ends because that would block the wands flow of energy. Some people paint or varnish their wands, some people custom make their own wands, choosing what wood to use, what length and thickness, etc.
No , they cannot cast real Harry Potter magic.
